Short summary
Organic triplets are an important class of aqueous photooxidants, but little is known about their reactions with most atmospheric organic compounds. We measured the reaction rate constants of a model triplet with 17 aliphatic alkenes; using their correlation with oxidation potential, we predicted rate constants for some atmospherically relevant alkenes. Depending on their reactivities, triplets can be minor to important sinks for isoprene- and limonene-derived alkenes in cloud or fog drops.
